Thanks Simon Bridge, im already seen before the wikipedia article but is the only place until now im read about spinor space as a complex vector space, because of this i had a doubt about the statement.

(1) So complex vector space and spinor space are the same thing or spinor space are a particular case of a complex vector space?

(2) Im still dont found a book which make that connection (about spinor space and complex vector space) can you indicate me one?

You might want to look at the multiplication table / matrix structure to understand the algebra in specific detail.

It also helps to look at complex numbers in terms of Grassmann algebras (exterior/inner products and bi-vectors) and in the different high level complex number algebras in a variety of dimension and understanding the geometric meaning of how the multiplication tables correspond to rotations and scaling in a particular space.

The linear algebra decomposition of a space in terms of rotation, scaling, and possible translation can help visualize what is really going on.
